QUEWZ-92 is a microcomputer analysis tool for planning and scheduling use in freeway work zone lane closures. It analyzes traffic conditions on a freeway segment with and without a lane closure in place and provides estimates of the additional road user costs and of the queuing resulting from a work zone lane closure. The road user costs calculated include travel time and vehicle operating costs. This report is a user’s manual for QUEWZ-92. After describing the capabilities and input data requirements of QUEWZ-92, it provides instructions on using Q92MENU, a menu-driven user interface, to run QUEWZ-92. It also includes three examples to illustrate the various input and output options that are available.
